Description

一种防磁场干扰式窃电电子电能表
技术领域
本发明涉及电能计量领域,具体的的说是一种防磁场干扰式窃电电子电能表。
背景技术
生产生活中,不法分子经常利用外部强磁场干扰电子式电能表计量精度,从而达到少计费目的。目前市场上流行的电子式电能表不具备防外加磁场干扰窃电功能。
发明内容
为有效解决上述问题,本发明提供了一种防磁场干扰式窃电电子电能表。
本发明是这样实现的:在市场上通用电子式电能表的基础上,加装一磁性触点开关,串接于内供电回路中,两端分别连接19接点、20接点。
本发明的有益效果是:结构简单,成本低廉,易于实现。
附图说明
下面结合附图作进一步说明。
图1是本发明的结构示意图。
图中1、19接点,2、20接点,3、磁性触点开关。
具体实施方式
如图所示,在市场上通用电子式电能表的基础上,加装一磁性触点开关3,串接于内供电回路中,两端分别连接19接点1、20接点2。
当磁性触点开关3感应到外部较强磁场时,19接点1、20接点2联通,切断供电回路。
